Made In the USA 100% brand new Radio knobs replacement for GMC Cadillac Chevrolet Chevy Chevrolet Suburban Silverado Tahoe Corvette Yukon Cadillac Escalade Sierra Replacement GM 16195409. Made from High quality material, guaranteed to fight tight and not fall off like the oem knobs. New replacement Knob Set, all 7 knobs are included. Volume - Power, SCV, Tune, Fade, Balance, Bass, Treble. These are replacements for the (7A123) knobs, fit Delco Electronics Radio, CD Player, and Tape players. The metal clip from old knob sometimes remains around the radio post. This clip is not needed for these new replacement knobs. Sometimes the old knobs will leave a small metal clip - sleeve around the radio knob post. I ask the customers to be sure to remove this clip before trying to slide the new knobs on. It is easily over looked and the new knobs will not slide over the old sleeve. Once this clip is removed the new knobs will have a secure tight fit, and will take some force to slide over the posts. The small knobs may take some adjustment to get the right alignment.
